The letter presents a new method for measuring small pulse modulated complex reflection coefficients of which both phase and magnitude are a rapidly varying function of time. The method is based on a single-point dynamic balance of two differently pulse-modulated signals produced in a modified reflection coefficient bridge. The measuring procedure is described in detail, and the first experimental results are discussed.
